ros_node.ros_node_from_pkg(pkg_name, node_name, launch_master=False, launch_master_term=True, launch_new_term=True, name=None, ns='/', output='log') → bool[source]

Function to launch a ROS node from a package.

Parameters

pkg_name (str) – Name of the package to launch the node from.
node_name (str) – Name of the node to launch.
launch_master (bool) – If ROSMASTER is not running launch it.
launch_master_term (bool) – If launch ROSMASTER do it in an external terminal.
launch_new_term (bool) – Launch the process in a new terminal (Xterm).
name (str) – Name to give the node to be launched.
ns (str) – Namespace to give the node to be launched.
output (str) – log, screen, or None.

Returns

True if the node was launched, False otherwise.

Return type

bool
